Anelok: Kinetis W-series

Nick mentioned on IRC this board that uses a Kinetis W-series
MCU:

I didn't know about this KW series, so I went to investigate.
A Kinetis-based radio could be interesting a) because the MCU
architecture would be familiar, and b) if USB is an option, too,
a single chip could do RF and be cMCU.
There are the following chips to consider: [1]
- KW01Z: sub-GHz only, used in the Orchard board, no USB
- KW2xD: 802.15.4 (wpan), no BT(LE), has USB option
- KW20Z: 802.15.4 (wpan), no USB, not yet available
- KW30Z, KW40Z: BTLE, no USB, not yet available
I inquired with Freescale support about availability and openness,
but they told me to ask a local distributor. Ah well.
In any case, it seems that no chip with both BTLE and USB is
planned.
